i will only be able to get on here a few more hours, so hope someone can help me out. there is no "factory tags" or paper work left on my truck.. ie.glove box.. so how can i find out which color TVS switches i need? when i bought the truck there wasn't any on it..its susposed to have them, and when i went to smog it the first time, i had to put them on..but i had no clue which color to get, i was able to narrow it down by studying a vaccume diagram so i knew how many ports each needed to have. but still there was several different colors to chose from. i beleave the different colors repersent temps that they work... so i bought the colors that the dealer sold the most of, but that doesn't necessarilly mean its the right color. so is there anyway to figure out what color my truck is susposed to have.
